[Solved]-HighCharts - show last labels in xAxis-Highcharts

In addition to the showLastLabel property, you may need to add the endOnTick flag to your example. For example:

//...

xAxis: [{
    type: 'datetime',
    showLastLabel: true,
    endOnTick: true
},

//...

Use tickPositions Array:(number) to specifically identify which indices you want displayed on your xAxis.
